Polyalkylbenzyl thiocyanates, upon irradiation in acetic acid, readily undergo reversible photoisomerization, giving an equilibrium mixture composed mostly of the corresponding isothiocyanates. Several new bis- and tris(isothiocyanatomethyl)polymethylbenzenes have been prepared by utilizing the photoinduced multiple thiocyanate isomerization.
聚烷基苄基硫氰酸酯在乙酸中照射后,很容易发生可逆的光异构化,得到主要由相应异硫氰酸酯组成的平衡混合物。利用光致多硫氰酸酯异构化制备了几种新的双和三(异硫氰酸根合甲基)多甲基苯。
